doclj
(do do-fn)Invoke the provided function, passing a snapshot of the test journal
Use this to perform side-effects without representing their result in the journal
Invoke the provided function, passing a snapshot of the test journal Use this to perform side-effects without representing their result in the journal
do!clj
(do! do-fn)Invoke the provided function, passing the journal ref
Use this to perform side-effects when you want to represent the result in the journal (e.g. insert test-data into an external database AND into the journal with the expectation that it will eventually appear in kafka via some external system like kafka-connect)
Invoke the provided function, passing the journal `ref` Use this to perform side-effects when you want to represent the result in the journal (e.g. insert test-data into an external database AND into the journal with the expectation that it will eventually appear in kafka via some external system like kafka-connect)
watchclj
(watch watch-fn)(watch watch-fn options)Watch the test-journal until the watch-fn predicate returns true
:watch-fn is a function that takes the journal and returns true once the journal
contains evidence of the test being complete
:options is an optional map containing additional information describing how the watch
function will be run. The following properties are supported.
:info Diagnostic information to be included in the response when a watch fails
to observe the expected data in the journal
:timeout The number of milliseconds to wait before giving up
Watch the test-journal until the `watch-fn` predicate returns true
`:watch-fn` is a function that takes the journal and returns true once the journal
contains evidence of the test being complete
`:options` is an optional map containing additional information describing how the watch
function will be run. The following properties are supported.

with-handlerclj
(with-handler machine handler)write!clj
(write! topic-id message)(write! topic-id message options)Write a message to the topic identified in the topic-metadata by topic-id
:message is typically a map to be serialized by the Serde configured in the topic-metadata
but it can be whatever the configued Serde is capable of serializing
:options is an optional map containing additional information describing how the test-message
should be created. The following properties are supported.
:key An explicit key to associate with the test message
:key-fn A function to derive the key from the test message
:partition The partition to which the test message should be written
:partition-fn A function to derive the partition to which the test message should be written
